図１Ａは実施形態に係る可搬式作業台１を示す正面図、図１Ｂは左側面図である。図１Ｃは実施形態に係る可搬式作業台１の一部を示す平面図である。
本実施形態に係る可搬式作業台１では、一対の梯子状の主脚２間に天板３の短手側が架け渡される。梯子状の主脚２は、一対の支柱２ａ間に複数本の踏桟２ｂが架設されて構成される。各主脚２は天板３に回動自在に取り付けられて、天板３の裏側に折り畳み収納可能になっている。天板３と主脚２との間には、途中で屈曲自在なステイ４が介装される。 Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
1A is a front view showing a portable workbench 1 according to an embodiment, and FIG. 1B is a left side view. FIG. 1C is a plan view showing a part of the portable workbench 1 according to the embodiment.
In the portable workbench 1 according to the present embodiment, the short side of the top plate 3 is bridged between the pair of ladder-shaped main landing gears 2. The ladder-shaped main landing gear 2 is configured by constructing a plurality of treads 2b between a pair of columns 2a. Each main landing gear 2 is rotatably attached to the top plate 3 and can be folded and stored on the back side of the top plate 3. A flexible stay 4 is interposed between the top plate 3 and the main landing gear 2.

天板３は矩形状の板材であり、その四隅には、断面矩形の管体からなる手掛かり棒５が立設される。手掛かり棒５は、作業者が主脚２を使って昇降したり、天板３上で作業したりするときに手を掛けるのに利用される。手掛かり棒５は、取付金具６を介して主脚２に取り付けられて、主脚２に沿って折り畳み収納可能になっている。
これら主脚２、天板３及び手掛かり棒５には、例えばアルミニウム合金が使用され、十分な強度を確保しつつ軽量化が図られている。 The top plate 3 is a rectangular plate material, and clue rods 5 made of a tubular body having a rectangular cross section are erected at its four corners. The clue rod 5 is used for the worker to put his / her hand when he / she moves up / down using the main landing gear 2 or works on the top plate 3. The clue rod 5 is attached to the main landing gear 2 via the mounting bracket 6 and can be folded and stored along the main landing gear 2.
For example, an aluminum alloy is used for the main landing gear 2, the top plate 3, and the clue rod 5, and the weight is reduced while ensuring sufficient strength.

ここで、図４、図５にドット模様で示すように、主脚２の踏桟２ｂと、天板３の端部のうち主脚２が取り付けられる短辺側の端部３ａとが着色されている。具体的には、主脚２の踏桟２ｂと天板３の端部３ａとが、カラーアルマイト処理又は塗装により黄色に着色されている。天板３の端部３ａにおいては、少なくとも上面３ｂと、踏桟２ｂの上方に位置する側面３ｃとがそれぞれ着色されるようにし、上面３ｂでは短辺に沿って帯状に着色される。なお、天板３及び主脚２における他の部位は、アルミニウム合金の地色となっている。 Here, as shown by the dot pattern in FIGS. 4 and 5, the tread 2b of the main landing gear 2 and the end portion 3a of the end portion of the top plate 3 on the short side side to which the main landing gear 2 is attached are colored. ing. Specifically, the tread 2b of the main landing gear 2 and the end portion 3a of the top plate 3 are colored yellow by color alumite treatment or painting. At the end 3a of the top plate 3, at least the upper surface 3b and the side surface 3c located above the tread 2b are colored, and the upper surface 3b is colored in a band shape along the short side. The other parts of the top plate 3 and the main landing gear 2 are the ground color of the aluminum alloy.

次に、天板３の上方の作業空間を、一対の長手側桟部材８、８と、一対の短手側桟部材９、９とにより囲む構成を説明する。
手掛かり棒５に被せるようにして、鞘管からなる支柱７が設けられる。支柱７は、例えば樹脂製の断面矩形の管体からなり、手掛かり棒５の外周面と密着する内周面を有する。手掛かり棒５と支柱７とは、例えば両者を貫通するボルトにより固定される。樹脂製の支柱７は、主脚２の踏桟２ａの色及び天板３の端部３ａの色に合わせて黄色にしている。
支柱７は、以下に詳述するように、天板３の四隅の手掛かり棒５を利用して、天板３の周縁部の上方において、天板３の長手方向に延伸する一対の長手側桟部材８、８と、天板３の短手方向に延伸する一対の短手側桟部材９、９とを支承するのに用いられる。 Next, a configuration will be described in which the work space above the top plate 3 is surrounded by a pair of longitudinal side rail members 8 and 8 and a pair of short side rail members 9 and 9.
A support column 7 made of a sheath tube is provided so as to cover the clue rod 5. The support column 7 is made of, for example, a resin-made tubular body having a rectangular cross section, and has an inner peripheral surface that is in close contact with the outer peripheral surface of the clue rod 5. The clue rod 5 and the support column 7 are fixed by, for example, bolts penetrating both of them. The resin column 7 is yellow to match the color of the tread 2a of the main landing gear 2 and the color of the end 3a of the top plate 3.
As described in detail below, the columns 7 are a pair of longitudinal crosspieces extending in the longitudinal direction of the top plate 3 above the peripheral edge of the top plate 3 by using the clue rods 5 at the four corners of the top plate 3. It is used to support the members 8 and 8 and the pair of short side rail members 9 and 9 extending in the lateral direction of the top plate 3.

支柱７の上部、換言すれば手掛かり棒５の上方には、一対の長手側桟部材８、８が取り付けられる。
長手側桟部材８は、例えば樹脂製の断面矩形の管体からなり、その両端が支柱７の上部に取付金具１０を介して回動可能に支持されるとともに、中央部で分割されている。これにより、長手側桟部材８の分割体８ａ、８ｂを、支柱７及び手掛かり棒５に沿うように折り畳み収納することができる。樹脂製の長手側桟部材８は、主脚２の踏桟２ｂの色及び天板３の端部３ａの色に合わせて黄色にしている。
そして、天板３の四隅で手掛かり棒５及びそれに伴って支柱７を立てた状態で、長手側桟部材８の分割体８ａ、８ｂを水平位置に回動させることにより、端面同士が衝合して、長手側桟部材８を架け渡した状態とすることができる。長手側桟部材８の分割体８ａ、８ｂは、例えばスライド構造の連結部材１１で脱着可能に連結される。 A pair of longitudinal crosspiece members 8 and 8 are attached to the upper part of the support column 7, in other words, above the clue rod 5.
The longitudinal cross-section member 8 is made of, for example, a resin-made tubular body having a rectangular cross section, and both ends thereof are rotatably supported on the upper portion of the support column 7 via a mounting bracket 10 and are divided at a central portion. As a result, the divided bodies 8a and 8b of the longitudinal rail member 8 can be folded and stored along the support columns 7 and the clue rods 5. The resin-made longitudinal rail member 8 is yellow to match the color of the tread 2b of the main landing gear 2 and the color of the end portion 3a of the top plate 3.
Then, with the clue rods 5 and the columns 7 standing at the four corners of the top plate 3, the split bodies 8a and 8b of the longitudinal rail member 8 are rotated to the horizontal positions so that the end faces abut against each other. Therefore, the longitudinal side rail member 8 can be bridged. The divided bodies 8a and 8b of the longitudinal crosspiece member 8 are detachably connected by, for example, a connecting member 11 having a slide structure.

長手側桟部材８には、それぞれ短手側桟部材９が取り付けられる。なお、一対の短手側桟部材９は、その形状や周辺構造（長手側桟部材８への取り付け構造や係止構造）について、天板３の中心に対して点対称の関係を有する。
長手側桟部材８（分割体８ａ）の架け渡した状態での上面（以下、単に上面と呼ぶ）８ｃには、支柱７に近い位置で、短手側桟部材９の基端部９ａが回動可能に支持される。短手側桟部材９は、例えばアルミニウム合金又はステンレス鋼等の金属棒で形成され、図２に示すように、基端部９ａを下向きに９０度に折り曲げ、長手側桟部材８への回動支持部として利用する。
このように長手側桟部材８の上面８ｃで短手側桟部材９の基端部９ａが回動可能に支持されるので、短手側桟部材９を、長手側桟部材８に沿うように収納することができる。また、長手側桟部材８を架け渡した状態とした場合、該長手側桟部材８で支持される短手側桟部材９は垂直軸まわりに回動可能であり、対向位置の長手側桟部材８に向けて水平方向に回動させることができる。 A short side rail member 9 is attached to each of the long side rail members 8. The pair of short side rail members 9 have a point-symmetrical relationship with respect to the center of the top plate 3 in terms of their shape and peripheral structure (attachment structure to the longitudinal side rail member 8 and locking structure).
On the upper surface (hereinafter, simply referred to as the upper surface) 8c of the longitudinal side rail member 8 (divided body 8a) in a bridged state, the base end portion 9a of the short side rail member 9 is rotated at a position close to the support column 7. It is movably supported. The short side rail member 9 is made of a metal rod such as an aluminum alloy or stainless steel, and as shown in FIG. 2, the base end portion 9a is bent downward at 90 degrees and rotated to the long side rail member 8. Used as a support.
In this way, the base end portion 9a of the short side rail member 9 is rotatably supported by the upper surface 8c of the long side rail member 8, so that the short side rail member 9 is aligned with the long side rail member 8. Can be stored. Further, when the longitudinal side rail member 8 is stretched over, the short side rail member 9 supported by the longitudinal side rail member 8 can rotate around the vertical axis, and the longitudinal side rail member at the opposite position is located. It can be rotated horizontally toward 8.

また、図２に示すように、短手側桟部材９の先端部も下向きに９０度に折り曲げ、長手側桟部材８への係止突起９ｂとして利用する。
図３に示すように、長手側桟部材８（分割体８ａ）の上面８ｃには係止孔１２が形成されており、自身で支持する短手側桟部材９の係止突起９ｂを挿入することができる。これにより、短手側桟部材９を収納した状態で保持することができる。
また、図４に示すように、長手側桟部材８（分割体８ｂ）の上面８ｃには係止孔１３が形成されており、対向位置の長手側桟部材８で支持される短手側桟部材９の係止突起９ｂを挿入することができる。すなわち、短手側桟部材９を対向位置の長手側桟部材８に向けて水平方向に９０度程度回動させることにより、短手側桟部材９の係止突起９ｂを係止孔１３に挿入することができる。これにより、短手側桟部材９を架け渡した状態で保持することができる。 Further, as shown in FIG. 2, the tip end portion of the short side rail member 9 is also bent downward at 90 degrees and used as a locking projection 9b to the long side rail member 8.
As shown in FIG. 3, a locking hole 12 is formed in the upper surface 8c of the longitudinal side rail member 8 (divided body 8a), and the locking projection 9b of the short side rail member 9 supported by itself is inserted. be able to. As a result, the short side rail member 9 can be held in a stored state.
Further, as shown in FIG. 4, a locking hole 13 is formed in the upper surface 8c of the longitudinal rail member 8 (divided body 8b), and the short side rail supported by the longitudinal rail member 8 at the opposite position. The locking projection 9b of the member 9 can be inserted. That is, the locking projection 9b of the short side rail member 9 is inserted into the locking hole 13 by rotating the short side rail member 9 in the horizontal direction by about 90 degrees toward the longitudinal side rail member 8 at the opposite position. can do. As a result, the short side rail member 9 can be held in a stretched state.

なお、図２に示すように、短手側桟部材９の適所をコ字形に突出させて取手部９ｃを形成するようにしてもよい。取手部９ｃの突出幅は、突出により形成される空間に指先が差し入れやすいものであると同時に、作業台全体を折り畳んだときに邪魔になることのない程度のものに設定する。 As shown in FIG. 2, the handle portion 9c may be formed by projecting an appropriate position of the short side rail member 9 in a U shape. The protruding width of the handle portion 9c is set so that the fingertips can be easily inserted into the space formed by the protrusion, and at the same time, it does not get in the way when the entire workbench is folded.

ここまで説明した構成においては、天板３の四隅で手掛かり棒５及びそれに伴って支柱７を立てた状態で、一対の長手側桟部材８、８を架け渡すことを前提として、一対の短手側桟部材９、９を架け渡すことができる。
本実施形態に係る可搬式作業台では、図５に示すように、一対の長手側桟部材８、８のうちの片方だけを架け渡した状態でも、一対の短手側桟部材９、９を架け渡すことができるようになっている。
以下、一対の長手側桟部材８、８のうち、架け渡した状態の長手側桟部材を一方の長手側桟部材８Ａと記し、支柱７及び手掛かり棒５に沿うように収納した状態の長手側桟部材を他方の長手側桟部材８Ｂと記して、詳細を説明する。 In the configuration described so far, it is assumed that the pair of longitudinal crosspiece members 8 and 8 are bridged with the clue rod 5 and the support column 7 erected at the four corners of the top plate 3, and a pair of short hands. Side rail members 9 and 9 can be bridged.
In the portable workbench according to the present embodiment, as shown in FIG. 5, the pair of short side rail members 9 and 9 are provided even when only one of the pair of longitudinal side rail members 8 and 8 is bridged. It can be crossed over.
Hereinafter, of the pair of longitudinal rail members 8 and 8, the longitudinal rail member in a state of being bridged is referred to as one longitudinal rail member 8A, and the longitudinal side in a state of being stored along the support column 7 and the clue rod 5. The crosspiece member will be referred to as the other longitudinal crosspiece member 8B, and the details will be described.

一方の長手側桟部材８Ａで支持される短手側桟部材９は、既述したとおり、対向位置の他方の長手側桟部材８Ｂに向けて水平方向に回動させることができる。
しかしながら、他方の長手側桟部材８Ｂは、支柱７及び手掛かり棒５に沿うように収納されているため、係止孔１３の位置が、短手側桟部材９の係止突起９ｂを挿入することができない位置となっている。 As described above, the short side rail member 9 supported by one long side rail member 8A can be rotated in the horizontal direction toward the other long side rail member 8B at the opposite position.
However, since the other longitudinal rail member 8B is housed along the support column 7 and the clue rod 5, the position of the locking hole 13 is such that the locking projection 9b of the short side rail member 9 is inserted. It is in a position where it cannot be done.

そこで、本実施形態では、取付金具１０（分割体８ｂを支持する取付金具）の頂面に、短手側桟部材９の係止突起９ｂを挿入する係止孔１４を形成している。係止孔１４は、長手側桟部材８を架け渡した状態、及び長手側桟部材８を支柱７及び手掛かり棒５に沿うように収納した状態のいずれにおいても位置が不変であり、本発明でいう短手側桟部材を係止するための係止部に相当する。これにより、短手側桟部材９を対向位置の他方の長手側桟部材８Ｂに向けて水平方向に９０度＋α程度回動させることにより、その先端部の係止突起９ｂを係止孔１４に挿入することができる。なお、αは、係止孔１３と係止孔１４との位置ずれ（図４を参照のこと）に相当する角度を意味する。 Therefore, in the present embodiment, a locking hole 14 for inserting the locking projection 9b of the short side rail member 9 is formed on the top surface of the mounting bracket 10 (the mounting bracket that supports the split body 8b). The position of the locking hole 14 does not change in both the state in which the longitudinal rail member 8 is bridged and the state in which the longitudinal rail member 8 is housed along the support column 7 and the clue rod 5, and the position of the locking hole 14 does not change in the present invention. It corresponds to a locking portion for locking the short side rail member. As a result, the short side rail member 9 is rotated horizontally by about 90 degrees + α toward the other longitudinal side rail member 8B at the opposite position, so that the locking projection 9b at the tip thereof is made into the locking hole 14. Can be inserted. Note that α means an angle corresponding to the positional deviation between the locking hole 13 and the locking hole 14 (see FIG. 4).

この場合に、図６に示すように、取付金具１０と長手側桟部材８との取付構造によっては、取付金具１０の頂面の係止孔１４の下部が長手側桟部材８により閉ざされてしまう。そこで、長手側桟部材８を支柱７及び手掛かり棒５に沿うように収納した状態では、係止孔１４が閉ざされないように長手側桟部材８の端部に逃げ８ｄを形成する等しておく。
なお、係止孔１３と係止孔１４とは、理論上は係止突起９ｂの移動軌跡上、すなわち短手側桟部材９の基端部９ａを中心とする同円上に配置する必要があるが、各部の遊びにより係止突起９ｂを挿入できるのであれば、必ずしも同円上になくてもよい。 In this case, as shown in FIG. 6, depending on the mounting structure of the mounting bracket 10 and the longitudinal rail member 8, the lower portion of the locking hole 14 on the top surface of the mounting bracket 10 is closed by the longitudinal rail member 8. It ends up. Therefore, in a state where the longitudinal rail member 8 is housed along the support column 7 and the clue rod 5, a relief 8d is formed at the end of the longitudinal rail member 8 so that the locking hole 14 is not closed. back.
The locking hole 13 and the locking hole 14 need to be theoretically arranged on the movement locus of the locking projection 9b, that is, on the same circle centered on the base end portion 9a of the short side rail member 9. However, if the locking projection 9b can be inserted by the play of each part, it does not necessarily have to be on the same circle.

一方、他方の長手側桟部材８Ｂで支持される短手側桟部材９は、水平軸まわりに回動可能であり、対向位置の一方の長手側桟部材８Ａに向けて垂直方向に回動させることができる。
この場合、短手側桟部材９の係止突起９ｂは、対向位置の一方の長手側桟部材８Ａの上面８ｃに形成された係止孔１３に対して９０度位相がずれた位置関係となる。
そこで、本実施形態では、図２に示すように、短手側桟部材９の先端部に、係止突起９ｂとは９０度位相をずらしたかたちで第２の係止突起９ｄを設けている。これにより、短手側桟部材９を対向位置の一方の長手側桟部材８Ｂに向けて垂直方向に回動させることにより、その先端部の第２の係止突起９ｄを係止孔１３に挿入することができる。なお、本実施形態では、係止突起９ｂが本発明でいう第１の係止部に相当し、第２の係止突起９ｄが本発明でいう第２の係止部に相当する。 On the other hand, the short side rail member 9 supported by the other longitudinal rail member 8B is rotatable around the horizontal axis and is rotated in the vertical direction toward one longitudinal rail member 8A at the opposite position. be able to.
In this case, the locking projection 9b of the short side rail member 9 has a positional relationship that is 90 degrees out of phase with the locking hole 13 formed in the upper surface 8c of one of the longitudinal side rail members 8A at the opposite position. ..
Therefore, in the present embodiment, as shown in FIG. 2, a second locking projection 9d is provided at the tip of the short side rail member 9 so as to be 90 degrees out of phase with the locking projection 9b. .. As a result, the short side rail member 9 is rotated in the vertical direction toward one of the longitudinal side rail members 8B at the opposite position, so that the second locking projection 9d at the tip thereof is inserted into the locking hole 13. can do. In the present embodiment, the locking projection 9b corresponds to the first locking portion in the present invention, and the second locking projection 9d corresponds to the second locking portion in the present invention.

本実施形態に係る可搬式作業台１は、一対の長手側桟部材８、８及び一対の短手側桟部材９、９で四方を囲んだ使用状態と、一対の長手側桟部材８、８のうちの片方及び一対の短手側桟部材９、９で三方を囲んだ使用状態とに選択的に設置することができる。
通常の使用状態では、四方を囲んだ状態とすることにより、天板３に立つ作業者は、上半身がいずれかの桟部材８、９に近づいたときには天板３の周縁部に近い位置に立っていることを感知することができる。そして、天板３の長手側を壁面等に近接させる使用状態では、壁面側の長手側桟部材８を収納状態として、作業性を高めることができる。このときも、壁面側以外の三方では、天板３に立つ作業者は、上半身がいずれかの桟部材８、９に近づいたときには天板３の周縁部に近づいていることを感知することができる。 The portable workbench 1 according to the present embodiment is in a state of being surrounded on all sides by a pair of longitudinal rail members 8 and 8 and a pair of short side rail members 9 and 9, and a pair of longitudinal rail members 8 and 8. It can be selectively installed in a usage state in which one of them and a pair of short side rail members 9 and 9 surround three sides.
In the normal use state, by enclosing all four sides, the worker standing on the top plate 3 stands near the peripheral edge of the top plate 3 when the upper body approaches any of the crosspiece members 8 and 9. You can sense that you are. Then, in the usage state in which the longitudinal side of the top plate 3 is brought close to the wall surface or the like, the longitudinal side rail member 8 on the wall surface side can be stored to improve workability. Also at this time, on three sides other than the wall surface side, the worker standing on the top plate 3 may detect that the upper body is approaching the peripheral edge of the top plate 3 when approaching any of the crosspiece members 8 and 9. can.

なお、本実施形態に係る可搬式作業台１では、二方を囲んだ使用状態とすることも可能である。例えば一対の長手側桟部材８、８を掛け渡し、一対の短手側桟部材９、９を収納した状態とすることができる。或いは、一対の長手側桟部材８、８を収納し、一対の短手側桟部材９、９を掛け渡した状態とすることができる。すなわち、一対の長手側桟部材８を収納した状態では、短手側桟部材９を対向位置の長手側桟部材８に向けて垂直方向に回動させることができ、その先端部の係止突起９ｂを、取付金具１０の頂面の係止孔１４に挿入することができる。
さらにいえば、一対の長手側桟部材８、８及び一対の短手側桟部材９、９のうちいずれか１本だけを掛け渡した使用状態とすることもできる。 The portable workbench 1 according to the present embodiment can be used so as to surround both sides. For example, a pair of longitudinal side rail members 8 and 8 can be hung and a pair of short side rail members 9 and 9 can be housed. Alternatively, the pair of longitudinal side rail members 8 and 8 can be housed, and the pair of short side rail members 9 and 9 can be hung. That is, in the state where the pair of longitudinal rail members 8 are housed, the short side rail member 9 can be rotated in the vertical direction toward the longitudinal rail member 8 at the opposite position, and the locking projection at the tip thereof can be rotated. 9b can be inserted into the locking hole 14 on the top surface of the mounting bracket 10.
Furthermore, it is also possible to use only one of the pair of longitudinal rail members 8 and 8 and the pair of short side rail members 9 and 9.

長手側桟部材８及び短手側桟部材９を含む各部の形状や構造は一例に過ぎず、これに限定されるものではない。例えば手掛かり棒５に支柱７を別途設ける構成を説明したが、手掛かり棒５で直接的に一対の長手側桟部材８、８及び一対の短手側桟部材９、９を支承するような形態としてもよい。 The shape and structure of each part including the long side rail member 8 and the short side rail member 9 are merely examples, and the present invention is not limited thereto. For example, the configuration in which the support column 7 is separately provided on the clue rod 5 has been described, but as a form in which the clue rod 5 directly supports the pair of longitudinal side rail members 8 and 8 and the pair of short side rail members 9 and 9. May be good.

また、係止孔１３と係止孔１４とを別個に配設する構成としたが、それに限定されるものではなく、両者を共用とする形態としてもよい。例えば図６に一点鎖線で示すように、長手側桟部材８の上面８ｃであって、取付金具１０の頂面の係止孔１４の真下に対応する位置に穴１５を形成しておく。この場合、図６に示すように長手側桟部材８を架け渡した状態であっても、対向位置の長手側桟部材８で支持される短手側桟部材９の係止突起９ｂや第２の係止突起９ｄを係止孔１４から穴１５に挿入することができ、上記実施形態でいう係止孔１３は不要となる。 Further, although the locking hole 13 and the locking hole 14 are arranged separately, the present invention is not limited to this, and both may be shared. For example, as shown by the alternate long and short dash line in FIG. 6, a hole 15 is formed in the upper surface 8c of the longitudinal rail member 8 at a position corresponding to directly below the locking hole 14 on the top surface of the mounting bracket 10. In this case, even in a state where the longitudinal rail member 8 is bridged as shown in FIG. 6, the locking projection 9b of the short side rail member 9 supported by the longitudinal rail member 8 at the opposite position and the second The locking projection 9d can be inserted into the hole 15 from the locking hole 14, and the locking hole 13 in the above embodiment becomes unnecessary.

以上述べたように、本実施形態に係る可搬式作業台１では、主脚２の踏桟２ｂと、天板３の端部うち主脚２が取り付けられる端部３ａとを黄色にし、天板３及び主脚２における他の部位の色（アルミニウム合金の地色）と異ならせている。これにより、天板３に昇降し、天板３に立って作業するといった一連の動作を行う際に、主脚２の踏桟２ｂや天板３の端部３ａが確認しやすくなる。
具体的に述べれば、作業者が天板３に昇降する際に、踏桟２ｂの視認性が向上し、確実に踏桟２ｂに順次足をかけていくことができる。また、踏桟２ｂだけでなく、天板３の端部３ａも着色することにより、天板３の端部３ａを視認した上で、天板３に登ることができる。特に踏桟２ｂの色と、踏桟２ｂの上方に位置する端部３ａの色とを同色とすることにより、作業者は、同色の踏桟２ｂから同色の天板３の端部３ａへと戸惑うことなく自然に足をかけることができる。 As described above, in the portable work table 1 according to the present embodiment, the tread 2b of the main landing gear 2 and the end portion 3a of the end portions of the top plate 3 to which the main landing gear 2 is attached are colored yellow and the top plate is turned yellow. It is different from the color of other parts (ground color of aluminum alloy) in 3 and the main landing gear 2. This makes it easier to check the tread 2b of the main landing gear 2 and the end 3a of the top plate 3 when performing a series of operations such as moving up and down to the top plate 3 and standing on the top plate 3 for work.
Specifically, when the worker moves up and down on the top plate 3, the visibility of the tread 2b is improved, and the foot can be surely put on the tread 2b one by one. Further, by coloring not only the tread 2b but also the end portion 3a of the top plate 3, it is possible to climb the top plate 3 after visually recognizing the end portion 3a of the top plate 3. In particular, by making the color of the tread 2b and the color of the end 3a located above the tread 2b the same color, the operator can move from the tread 2b of the same color to the end 3a of the top plate 3 of the same color. You can step on naturally without any confusion.

また、天板３に立って作業する作業者は、天板３の端部３ａの位置を視認することができるので、上述したような桟部材８、９への接近の感知と合わせて、天板３上の作業領域を容易に把握できるようになる。
本実施形態では、天板３の端部うち主脚２が取り付けられる短辺側の端部３ａ、換言すれば昇降位置となる端部３ａだけに着色している。天板３上で作業している間に、作業者は何度も向きを変えることがあり、天板３にどの辺が昇降位置であったかが瞬間的に判断できなくなることもありえる。この場合でも、天板３の着色された端部３ａを視認するだけで、昇降位置を容易に把握することができる。 Further, since the worker standing on the top plate 3 can visually recognize the position of the end portion 3a of the top plate 3, the ceiling is combined with the detection of the approach to the crosspiece members 8 and 9 as described above. The work area on the plate 3 can be easily grasped.
In the present embodiment, only the end portion 3a on the short side to which the main landing gear 2 is attached, that is, the end portion 3a which is the elevating position, is colored among the end portions of the top plate 3. While working on the top plate 3, the worker may change the direction many times, and it may not be possible to momentarily determine which side of the top plate 3 was in the elevating position. Even in this case, the ascending / descending position can be easily grasped only by visually recognizing the colored end portion 3a of the top plate 3.
